Read about them, and ask people who have them first.
Bear in mind do you have the ground to work the dog, what ground is it (flinty etc), large open fields, small paddock
type fields, can you afford to pay vet fees!
You need to take all that into account. Hope you find a nice type to hunt with that suits you.
The trend at the moment are those Bull x's, i hear you get 1 crate of Stella, and a large collar with the dogs name written in HUGE writting on it with each pup sold, but hurry, this offer ends in 2 weeks.
